OIL-BURNER.

To all 'whom it may concern Bei. it known that we, JAMES D'. GOODWIN and GROVER C. GOODWIN, citizens of the United States, residing at Richmond, in the county of Henrico and State OfVirginia, have invented certain new and usefulcImprovements in Oil-Burners, of which the following is a specification.

Our invention relates to new and useful improvements in burners.

The object of our invention is to provide a retort burner in which the voil is more readily converted into gas and more evenly distributed throughout the burner tube, so that better combustion is obtained and in which there is practically no odor due to the waste of oil.

Another object of our-invention is to pro- Vide a burner of this character, in which the oil is more readily converted into gas without unduly heating the generating pipes and having means whereby the gas pressure can be easily controlled, so as to Obtain the proper mixture of air and gas to cause more perfect combustion.

A still further object of our invention is to 'provide a burnerof this character which l is complete in'itself and can be readily aptends the entire length of the base. This y trough is preferably filled with asbestosA plied at any place desired to be heated.

These and other objects will in part be obvious and will in part be hereinafter moreV fully described. t

ln the accompanying drawings: Figure 1 is a perspective View of an ordinary cook stove, showingour invention, applied thereto; Fig. 2 is a top planl view of our improved retort burner;v Fig.v 3 is a horizontal sectionalview o'f Fig. 2; Fig. 4`is al vertical sectional view taken at right angles to Fig. 3.

Referring now to the drawings,` 1 represents the base of our improved burner, which, as shown, is-O an elongated troughlike form, having at each end the legs-2 andv 3 by 'means of which it is supportedy upon the grate or the bottom of any receptacle in.

which the burner is'to be placed. The bottom 4 of the trough is of an irregular form,l gradually curving toward Aone side, and provided adjacent its lower side with 1a vertical partitionv 5forming a trough 6 Whichex- WoolY and forms a wick for startingV the bul-nenas will lbe later described. The par-j tition15 is provided with Openings 7 to allowA l Patented June 27, 1916.

any oil that may leak from the burner to pass downwardly into the trough where it 1s absorbed by the asbestos wool. The bottom 4 of the base is provided with a trough 6 directly below the generator and like the `trough 6 has asbestos wool therein, and

serves as anadditional heater.

The upper edges of the ends 8V and 9P of the base 1 are provided with curved recesses 10 and in which rests the distributing tube 11, by which it is supported. At one end of the distributer tube is a head 12, which has at its center an inwardly extending cylindrical member 13 enterin the tube 11. The head 12, on the outside t ereof, is prol vided with an outwardly extending cyliny drical member 14 in alinement with the cylindrical member 13, and provided at its outer end with the enlarged mixing chamber 15. The mixing c hamber has at its end a series of openings 16, andthe passage of air therethrough is regulated -by the shutter 17, which is oscillated on the mixing chamber and provided with openings 18, correspondin with the openings 16. The shutter is he dh upon the mixing chamber 15 by means ofthe screw 19, and operated by means of the handle 20. The .center of the shutter, and also the end of the mixing chamber is provided with an opening 21 through which the gas supply'pipe 22 extends, -as Willbe-v later described.

The opposite end of the tube 11 enters'an l i inwardly extending lcylindrical portion 23 l carried byjltlhe head 24. ,This supporting head is-pi-'Ovided at its center with an outwardly extending cylindrical portion 25 which; rests in thesemi-circular. recess 10 in the end`9 of the base 1. The tube L1, as I shown in Fig. 3, extends but a slight distance within the cylindrical portion 23 of y A the head 24, and the headA 24 beingrigidly supportedI allows 'for the expansion'of the tube 11 independently of. the head. "The heads 12' and 24, adjacent theirouter ,pe-

' riphery, are provided with'inwa-rdly extending -annular flanges 26 and 27 which extend 29 arrangedfopposite the lugs 30 carried by the heads 12 and? 24 and the saidlugs are Vlocked together by means. of the bolts 31. By this vstructure it will be seenthat the" burner tube 28 kisfclamped to the heads 12 *620* certain amount of oil having previously and 24 and the distributing tube is supported ConcentricallyI therein, as fully shown in F ig. 3 of the drawings. The burnertube 28 is provided with a series of slots 32, which allows the gas to pass therefrom and to burn. While we have shown the lgas discharge from the burner tube in the form of slots7 it will be understood that any form of openings. could be used without departing from my invention.

Extending longitudinally of the base 1 within the trough 6, is the retort tube 33, which has at its outer end a valve 34 and an oil supply pipe 35. By this valve, it will be seen that the amount of oil fed to the retort tube may be readily controlled. The opposite end of the retort tube 33 extends through an opening 36 in the base l andlis curved upwardly at 37 and rests in insemicircularl recess in a lug 38 carried by the end of the base and said tube is extended forwardly at 39 parallel with the burner tube 28 a slight distance thereabove. The forward endof the tube 39 has-a downwardly extending portion 40 which communicates with a pipe 41 and is connected to the pipe 22 extending into the mixing chamber l5. The supply of gas from the reto-rt tube 39 to the .tube 22 is controlled by the valve 42. The burner tube 28 below the retort tube 39 has a longitudinally depressed portion 43 and is provided with openings 44 to allow for a small flame below the retort tube for heating the same.

The mixing tube 11 is provided in its lower face with three openings 45, 46 and 47. The opening 46 at the center is the larger, the'opening 47 the next larger and lthe opening the smallest. These openings are to allow the gas to pass therefrom to the burner tube 28. Surrounding the opening on the lower face of the distributingtube 11 are guideways 48, in which areal-ranged the slides 49, by means of which the size of the openings for the discharge of the gas may be regulated. Connected to the slides 49 is a rod 50 which extends outwardly through the head 12 and is provided with a h/andle 51, by means of which the slides may be operated from the outside. The tubel 11, as shown in Fig. 3 of the drawings, is of a tapering formr gradually increasing in diameter toward itsrear end, so that the gas will be more evenly distributed from the tube 22 and thus cause an even supply of gas to the burner tube 28.

In the operation of the device the valve "34 isfirst opened allowing the oil to pass from the tube 35 to the retort tube 33. A

been placed in the trough 6 and ignited, the tube 33 has become heated andthe oil is vconverted into gas. The gas passes upwardly through the curved portion 37 to the tube 39, and is-more thoroughly 'heated producing a more combustible gas. The gas passes downwardly from the retort tube 39, through the valve 42, to the tube 22. From the tube 22 it is injected into the tube Cl1 drawing the necessary amount ot'4 air through the openings 16. rlhe mixture passes downwardly through the openings 45, 4.6 and 47 into the burner tube 28 from which it is discharged through the openings 32 and is burned. Any oil which may not have been converted into gas which passes downwardly through the tube 4() would drip down from around the shutter 17 and enter the cup 52 supported by the tube which extends inwardly and communicates with the curved bottom of the support 1. Thus it will be seen that any oil that is not vaporized in the retort tube will pass to the trough 6 and be absorbed by the asbestos wool and there will be no odor therefrom. By the construction and arrangement of the several parts, it has been found that the oil is more readily converted into gas and the gas properly mixed with air to form a more combustible gas and almost entirely dispenses with any odor which usually exists in retort burners of this ikind. By the specie arrangement of the burner tube and the mixing tube either one can expand to a Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is:
